To all whom it may concern.-

Be it known that I, THEoDoRE A. STARK, of Ottawa,in the county of La Salle and State of Illinois, haveinventeda new and Improved Motor, of which the following is a full, clear, and exact description.

My invention relates to improvements in motors, and the object of my invention is to produce an extremely simple motor, which is adapted to be operated by the hands and feet of a person, which is provided with reciprocating slides actuated by the hands or feet, and having means for converting their reci procating strokes into continuous rotary motion, which is very light, strong and durable, which is adapted for use as an exercising machine, as it brings all the muscles of the body into play, and which may be made useful for driving flying machines, bicycles, boats, and other things which do not require a great amount of power.

To this end, my invention consists in a mo tor, the construction of which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the motor embodying my invention, showing it as applied to a flying machine; Fig. 2 is an end view of the same; Fig. 3 is an enlarged detail side elevation of the motor proper; Fig. 4: is a cross section on the line 4 4 in Fig. 3. Fig. 5 is a broken enlarged plan of the main bar, the driving cable, and one of the slides which operates the cable, and Fig. 6 is a plan view of the machine with the aeroplane removed.

The frame of the motor consists of a straight bar 10, which is preferably hollow to give it the necessary lightness, and this bar has centrally therein an opening 11, extending sidewise through'it, and in this opening or slot is a driving pulley 12, which is preferably grooved, and is secured to a driving shaft 13, which is journaled in the bar 10 and extends above and below the same, the shatt having on its ends hanged pulleys 14, which are driven by an endless belt 15, this being wound once or twice around the pulleys to prevent it from slipping. The belt is also held to run over antifriction or guide pulleys 16, which Serial No. 4:35,'729. (No model.)

are also grooved and which are held at the ends of the bar 10, the pulleys being journaled in forks 17 having shanks 17, which extend into the ends of the bar, and the forks are held in position by set screws 18, which are held to turn in the bar and impinge upon the fork Shanks. By this means the forks and pulleys may be adjusted so as to give the proper tension to the belt.

On the bar 10 near the ends, are slides 19, which move easily on the bar, one being adapted to be operated by the hands and the other by the feet 0E a person, and each slide is provided on itsupper and lower sides with projecting abutments 20, which have square shoulders at right angles to the belt 15, and the abut-men ts are oppositely arranged,that is, the shoulder of one faces in one direction and the shoulder of the other iu the opposite direction. The abutlnents are grooved, as shown at 20, so that the belt 15 may be held within the groove, and each slide has adjacent to the shoulder of the abutment a swinging leaf or link 21, through which the belt 15 extends. It will thus be seen that when the slide is pulled in one direction, the leaf on one side will swing up against the abutment, and the slide will move freely along the belt and rod Without actuating the belt, but when moved in the other direction, the leaf or link will bind the belt between the leaf and the abutment, and consequently the movement of the slide will be imparted to the belt.

One slide has laterallyextending handles 22, which are adapted to be clasped by the hands of the operator, and the other slide has pedals 23, in which the feet of the operator may be inserted, and the feet may be secured to the pedals by means of any suitable straps.

In Figs. 1 and 2, I have shown the applica` tion of the motor to a liying machine, but it Will be understood that it may be used for other purposes. As here shown, the motor is suspended in a light open frame 23, which extends transversely to the bar 10, and is tapered at the ends, this frame having an open central space large enough to receive the body of the operator, and the frame is suspended from an aeroplane 24:, which may or may not be inflated, as desired. At the ends of the frame 23L are revoluble propelling wheels 25, these being formed of a series of radially-ex- IOO tending blades, and the hubs of the propellers are provided'with grooved pulleys 525, which connect by means of a belt 26 with the driving pulley 12, so that the movements of the pulley may be transmitted to the propellers and the ilying machine operated. The blades of the propellers are arranged-'at su ch an'angle that they will lift upward on the machine and at the same time move it forward. Themotorj may however, be attached to any kind of a flying machine.

places himself within the frame'fZSn and above the bar 10, his body being extendedlin-a nearly parallel position to the bar, and his body is suspended by means of 'a suitable belt attach- "mentfaround his waist,.anysuitable harness beingemployed for this purpose. THe then graspsthe `handles `2`2o'f -one slide with fhis hands, has'hisffeet securedfto-'theslide onithe otherside ofthe'driving pulley l12, Aand *per- The ,arrangementfof the slides and leave's'21,1with their oppositely arrangedabutments` is suchthat when-'the slides arepulled towardthe center of the bar, the upperleaf 2l on the :foot slide will pull lforward on the beltl, moving it in the direction indicated by thefarrowsfand the lower leaf 21'of the'- 'h'and' slide will pull'inlthe' opposite direction 35 onfthelower strand of the belt, thusmoving the'whole body of the belt in the same ydirec-v tion, .and Whenthe slides are 'pushed apart,

th'ereverse'action takes place `so as ltoA keep `th'ebelt moving` in the same.direction,that fis to say, the ylower-leaf 21 of the footslide; lwill :pullupon the' lower -strand of the belt, 1 andthe upper leaf' of the-hand slide'willpullvupon 'thefupper strand ofith'e belt, as'shown In constructing the motor,'it"should be 'made ofvr as lightmaterialas possible,`andfthe 'movable parts should all be provided with some for-mf of" ball -bearings softhat they may; fmove with .as-little friction as possible.

Vmounted on-'the bar, each slide having on oppositelsidesabutments through which the belt Apasses,'andy hinged' leaves or grippcrsfadapted .to frictionally engage the belt and close againstthe abutments,substantially as described.

2. A motor, comprising a bar or frame having pulleys at its ends and a driving pulley in the center, an endless belt held to run over t-heend pulleys andto drive the center pulley, and movable slides mounted on the bar on opposite sides of the driving pulley, the slides having friction devices to engage the belt, substantially as described. It is operated as follows: The operator;

`A motor, comprisinga baror frame having a driving pulley arranged centrally therein vand flanged pulleys secured to opposite ends of the driving pulley shaft, anti-friction pulleys journaled-atitheends of the machine, an

endless beltfheld to runrovertheanti-friction pulleys and:arranged to drive the "-langed pulleys, andslid-es mounted vonrthe opposite fend portions of 'the bar ior:frame,1the slides having friction devices'adapted.` to engage the belt, substantiallyfasfdescribed.
